Paddle8, which launched in May, was conceived when former Phillips de Pury marketing director Alexander Gilkes noticed that friends who had the means to collect were frustrated by their lack of access to galleries and fairs. He teamed with curator Hikari Yokoyama and Delhi-born entrepreneur Aditya Julka to create a series of virtual group exhibitions. Every five weeks they ask a tastemaker to guest-curate an online show of about 20 works (like Scott Olson's Untitled, above) culled from various dealers, and then they post Web interviews and offer virtual studio visits to help newbies navigate the art world. Its roster of galleries includes both established names—Metro Pictures, Marianne Boesky, White Cube—and such up-and-comers as Museum 52 and James Fuentes.
Art.sy, designed to introduce collectors to new works based on their personal preferences and modeled on music sites like Pandora, has drawn such investor-advisers as Google chairman Eric Schmidt, Twitter cofounder Jack Dorsey, and gallerist Larry Gagosian. With Wendi Murdoch on the board and collector Dasha Zhukova the site's creative director, it had a splashy preview at Art Basel in June and plans to include works (like Yayoi Kusama's Kei-Chan, above) at a wide range of prices, including $1 million–plus. More than 160 galleries have signed on.
Other art sites drawing a new generation of collectors focus on carefully curated selections of specialty items. Gallerist Bill Powers's Exhibition A, for example, offers contemporary prints (including Les Rogers's Bright Bedroom, above), while 20X200—created in 2007 by New York gallerist Jen Bekman—features photographers such as William Wegman.
Grey Area, a new website by Kyle DeWoody (daughter of collector Beth Rudin DeWoody) and Web entrepreneur Manish Vora, sells functional objects designed by artists. And Blacklots, a 24-hour auction platform cofounded by Phillips de Pury's former London chairman, Rodman Primack, offers pieces by Elad Lassry, Takashi Murakami, Thomas Ruff, and Massimo Vitali, whose Vecchiano is above.
